Iscar 5621055 Ball End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ISCAR 5621055 is a solid carbide ball end mill designed for high-performance milling in demanding machining applications. With a 0.75 inch mill diameter and a 1.5 inch length of cut, this four-flute single-end tool is built for profiling, contouring, and finish milling on a wide range of workpiece materials. The submicron carbide grade substrate provides toughness and wear resistance, while the TiAlN coating adds thermal stability during high-speed cuts. A 30-degree right-hand helix and spiral flute geometry support efficient chip evacuation and smooth cutting action. Overall length is 5 inches with a 0.75 inch shank diameter.

This end mill is suited for use in CNC machining centers handling ferrous and non-ferrous materials across multiple material groups, including cast iron, stainless steel, general steels, and heat-resistant superalloys. The long-length designation makes it appropriate for applications requiring extended reach into pockets or complex profiles. Right-hand cutting direction is standard for conventional milling setups. It is installed and used by machinists and tooling specialists in production shops, job shops, and precision manufacturing environments.

Key Features

• Solid submicron carbide construction for high hardness and edge retention
• TiAlN coating for thermal resistance and extended tool life at elevated cutting speeds
• Four-flute spiral geometry with 30-degree right-hand helix for efficient chip removal
• Ball end profile for 3D contouring, profiling, and radius milling
• Single-end configuration with 0.75 inch shank diameter for standard toolholder compatibility
• Long-length series EBLI-A-4 for extended reach applications

Compatibility

Designed for use in CNC machining centers and mills accepting a 0.75 inch shank. Workpiece material compatibility codes H, K, M, P, and S indicate suitability for hardened materials, cast iron, stainless steel, general steels, and heat-resistant superalloys. Part of the ISCAR EBLI-A-4 series.

Installation Notes

Install in a precision toolholder rated for the 0.75 inch shank diameter and ensure proper runout before use. Power down and lock out the machine spindle before changing tooling. Verify toolholder clamping torque per the toolholder manufacturer specifications. Coolant-through is not supported on this tool; use external coolant or air blast as appropriate for the application.
